Summary
A rare giant thoracolumbar synovial cyst spanning three spinal levels was surgically removed from a 74-year-old woman presenting with chronic lumbar and leg pain. This case highlights diagnostic and therapeutic considerations for such extensive spinal cysts.
Area of Science:
- Spine surgery
- Neurosurgery
- Radiology
Background:
- Synovial cysts are rare spinal tumors, typically occurring in the lumbar region.
- Giant thoracolumbar synovial cysts involving multiple spinal levels are exceptionally uncommon.
Observation:
- A 74-year-old woman presented with chronic lumbar pain and left leg pain.
- Magnetic resonance (MR) imaging revealed a large extradural cyst extending from T12 to L2.
- Surgical excision of the cyst was performed, with microscopic examination confirming a synovial cyst.
Findings:
- This case represents a giant thoracolumbar synovial cyst spanning three metameric levels, a finding not previously reported in the literature.
- Diagnosis was confirmed through a combination of MR imaging and microscopic examination.
- The cyst was completely removed surgically.
Implications:
- This case expands the understanding of synovial cyst presentation and behavior in the thoracolumbar spine.
- Accurate diagnosis via advanced imaging like MRI is crucial for appropriate surgical planning.
- The report contributes to the discussion on the pathogenesis and optimal therapeutic strategies for extensive spinal extradural cysts.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
